This invention relates to manualot the multiple control type; the present application being a division of my copending application, Serial No. 324,993gflled March 20, 1940; I

Manual reset valves, of the type to which this invention relates; preferably employ electromag netic means for maintaining a main valve member in open position,5against a bias, only after it i has first been manually brought to that position. Such means has particular utility in the control of fuel to a fluid fuel burner; means responsive to the flame of the burner,'or toa pilot burner theree for, usually then being provided for controllingthe energization of the electromagnetic means; The flame responsive means mayfconsist 'of a thermoelectric generating device or a thermal cut-out controlling asuitable source of electrical energy. Upon extinction or the flame', theelectromagnetic means is deenergized and the valve closes; manual resetting of the. valve then being required for subsequent operation of the burner.

An object of this invention is toprovide, ina

whereby, a pilot burner can besupplied wit resetting operation ot'the main 11 fuel inthe valve and before outlet chamber, normal] plementalvalve means, within the main valve port so that the fluid can pass thereinto, independently oi the supplementa Other objects and advantages oi the invention will be found in the description, the drawing, and r the claims; and, for full vunderstanding oi the invention, reference may be had toethe following detaileddescription and accompanying drawing, wherein: l; ,1

If the upper plunger 22 is now moved downward by be limited only by the scope of the appended claims.

I claim as my invention:

1. In a fluid control valve: a casing having an inlet and a main outlet and a partition separating the same, said partition having a port opening therethrough provided at the inlet side of the partition with a valve seatga valve member cooperable with said seat and, biased to closed position, 'said'valve member'jineluding a portion of magnetic material, electromagnetic means coop- I erable with said portion, means extending to the Fig. 1 gas flow to both of the burners is obstructed e M said electromagnetic means, said electromagnetic pressure on the button 28, the rod 34 will be depressed and the member 32 brought into engageelectromagnetic means is subsequently retracted ment with the top surface of the lower plunger, as shown in Fig. 2. The supplemental valve member 35 now being open, gas can flow through .openings 31, bore 35, recess 38 and passageway M to the pilot-burner, where it may be lighted. As-

sumingthat a thermmelectricdeVice, electrically connected to the coil I8, is positioned so as to be heated by the'flame of the pilot burner, after a short period of time current will be generated by the device in an amount suflicient to energize the core, I8 to cause the plungers to be magnetically held in engagement with each other (th member 32being considered a'spart of the upper plunger) so that when the button 28 is released, the lower plungerswill be moved upwardwith the upper plunger, against the force of spring 21 which ob,- vio'usly must-be considerablylessthanthat of spring 29; the parts'as'suming the positions shown in Fig. 3. Itis to be understood that therewill -b e.a magnetic force tending toresist the sl iding of the plungers in the core,but-that forceis slight If the pilot burner flame is extinguished, upon cessationof current, generation bythe thermoelectric device, the .electromagnet is deenergized and the lower plunger falls under the force of spring 21,-closing the main valve. Pressure; on

the rod-being released, the supplemental valve 3 member 35 also closes. Fuel supply to bothtthe main and the'pilot burner is thus obstructed; re-

setting of the valve, as hereinbefore described,- being required to initiate further operation of the energized, the upper plunger ma be manually moved'both downward and upward without affecting the condition of the main valve. Only when the pilot burner is alight. and thus asafe condition exists, can the main valve be opened.

While I have herein shownv and described a specific embodiment of-my. invention as appliedto the control of a valve for fiuid fuel burners, it is obvious that my invention has other uses and that modifications may be made without departing from the spirit thereof. I intend therefore to exterior of said casing formechanically moving means, when energized being effective to magnetically hold said valve memberwhen moved into engagement with said portion so that when the the valve member is moved therewith to open position against the force of said bias, said casing also havinga supplemental outlet, means within said port opening defining a cup-shaped recess in comparison with the force tending to hold the abutting surface of the plungers together. .Also.-

communicating with saidsupplemental outlet, the mouth of said recessbeing so arranged that when said valve member is in engagement with saidseat. the mouth is closed thereby, the portion of the valve member which then closes saidmouth having a passage therethrough communicating with the inlet of the casing and providing a supplemental valve seat, a supplemental valve member cooper-able with said supplemental seat and biased to closed position, and means engageable bysaid electsomagnetic means in its movement toward said main valve member for moving said supplemental valve member to open position and for maintaining it inthat position while the elec tromagnet is energized. I a I n 2. In a fluid control valve: a casing having an inlet and a main outlet and apartition separating-the same, said, partition having a port opening therethrough provided at the inletsideof the partition with a valveseat, a valve vmembercooperable. with said seat and movable away from and toward thesame, means biasing said-valve member to closed position, an electromagnetfixed with respect to said casing and comprising a cor and an energizing coil therefor, said core havin a bore therethroughza rially aligned with said valve member, a firstmagnetic plunger connected to said valve member'and' having a portion reciprocable in the adjacent end of said bore, a second magnetic plunger reciprocable in the other end of saidbore.-.manual means operable exteriorly of the casing for moving said second plunger into engagement with said first plunger, said core being-adapted when energized to cause saidplungerstobe magnetically held together so thatwhensaid; second plunger is subsequently retracted said valve member is moved to open position; said casing also having asupplementai outlet, means defining a supplemental valve port arranged within said first-mentioned port opening and communicating with said supplemental outlet, and supplemental valve means associated with said first plunger for controlling fluid flow from said inlet to said-supplemental valve'port and operated to open position by the. movement of said second plunger toward said first plunger and maintained in that. position while the plungersare magnetically held together. i
